This thread is not about speed.  The OP wanted to experiment with
different solutions that are explicitly *not* optimal, for fun.

If you want a fast solution, just use a loop:

unset array
n=${#string}
for ((i=0; i<n; i++)); do array[i]=${string:i:1}; done

unicorn:~$ unset array; n=${#string}; for ((i=0; i<n; i++)); do 
array[i]=${string:i:1}; done
unicorn:~$ declare -p array
declare -a array=([0]="h" [1]="i" [2]=" " [3]="b" [4]="y" [5]="e" [6]=$'\t' 
[7]="w" [8]="h" [9]="y" [10]=$'\n' [11]=$'\E' [12]="[" [13]=";" [14]="1")
